The B.A. and the B.S. in biology can both provide students with the experience and knowledge necessary to have a successful career. A B.A. in biology requires 20 hours of approved hours in the Natural Sciences Division.The B.A. has a more flexible supporting area and is a particularly appealing option for students who would like to combine their biology degree with another area of emphasis such as math or physics.

This course is designed to introduce students to collegiate biology by teaching them how to carry out scientific research. Across all sections of this course, students will pose scientific questions, design and critique experiments, run those experiments, evaluate experimental outcomes, and communicate those outcomes. Within this framework of investigative inquiry, students will learn introductory content that will not only be meaningful for the current course, but will allow for a smoother transition to their sophomore year. Content areas include ecology, genetics, evolution, biodiversity, reproduction, development, and cellular/molecular mechanisms.
Course fluidly transitions between lecture and lab with an equivalency to 3 lecture hours and 3 laboratory hours per week. No P/F.Pre or corequisite(s): CHEM 1110 Chemical Principles I ; or prerequisite of CHEM 1100 Prep Chemistry.
(Multiple sections normally offered each semester.)
